* APR's Version
*
* There are several different mechanisms for accessing the version. There
* is a string form, and a set of numbers; in addition, there are constants
* which can be compiled into your application, and you can query the library
* being used for its actual version.
*
* Note that it is possible for an application to detect that it has been
* compiled against a different version of APR by use of the compile-time
* constants and the use of the run-time query function.
*
* APR version numbering follows the guidelines specified in:
*
* http://apr.apache.org/versioning.html
